I was also curious about the oatmeal and its supposedly negative effects Dr. Gundry was talking about. I've been eating oatmeal for a few years every morning and I'm not sure if I'm sick enough to believe his theory or healthy enough to disprove it. Anyhow, I'm going to keep eating my delicious oatmeal in the morning.

I prepare it somewhat different than most people. I use about 1000cc of water with a small cup of oatmeal. I slow boil it on mid-low temp (3.5 on my stove) with the lid partially open(slanted) for about 30-40 on timer. I use either steel cut or organic rolled oats. Afterwards, I add more boiling water to make it even more diluted and enjoy it. I don't know if anyone had tasted cooked rice with lots of water, but it tastes like that and it's so~~~ good. Thick oatmeal is too heavy for me and it's difficult to eat without some type of sweetener(usually raisins), but this way, I just enjoy the oatmeal by itself and it seems to help my acid reflux.
good to see other oatmeal lovers.
